Q: My daughter has an incredibly heavy back pack. How can I help her ward off pains when she grows up that may occur from years of this on going stress on her posture and muscles?
A: One thing to keep in mind, is that a long duration, low intensity stress is as damaging as a quick, high impact injury. The back pack is a low impact, repetitive, long duration stress. Carrying a heavy backpack long term, can make imbalances in the postural muscles such that the scalene muscles, pectoral muscles and psoas muscles are shortened causing forward head, rounded shoulder and lordotic low back posture.
